Bench Bleeding Clutch Master Cylinder

I'm getting ready to replace mine and I'm wondering if I have to bench bleed it like you like do with brake master cylinders. I have a mightyvac for bleeding the system when I'm done, but I'm wondering if I can do this by pulling all of the air out through the slave cylinder or some other way.

If I do have to bench bleed it, how the heck am I supposed to do that when clutch master is cylinder shares the brake reservoir?

You don't have to, at least I haven't had to.

You may wan to use the Mityvac to start getting fluid through the system, then bleed manually with an assistant. Can take a while to get all the air bubbles out and get the system happy, just watch your fluid level and keep at it.

Great! Thanks so much for your reply!

It's pretty easy to swap out. 2 12mm nuts on the inside of the firewall hold it in, one hardline going to it and the fluid line.

Most of the time is in bleeding it. Remove the aluminum belly pan under the transmission, makes it way easier.

Sounds simple enough to me. Now, if only my back would agree with the thought of digging under the dashboard. :-)

Thanks again!!

There is an aluminum belly pan under the transmission!?!! I don't have one of those.

But back to bleeding. Bench bleeding is easy so why not do it? You can run a vacuum hose from the bleeder nipple to the master reservoir if you have to do it by yourself.

BTW,I have an aluminum belly pan next time you come to town .

The clutch master doesn't have it's own reservoir, it has a hose that goes to the brake master cylinder reservoir. Make bench bleeding much harder with that, and I haven't really found a reason it needs to be done. Brake master, yes.
